Textbook Question
Chapter 6, Problem 26QTP
A simply supported rectangular beam is 25 mm wide and 1 m long, and it is subjected to a vertical load of 10 kg at its center. Assume that this beam could be made of any of the materials listed in Table 6.1. Select three different materials, and for each, calculate the beam height that would cause each beam to have the same maximum deflection. Calculate the ratio of the cost for each of the three beams.

Task 3
(a) A beam is to be fitted in a box of length of 2 m, width of 15 cm and height of 20 cm. Choose
a beam and specify its parameters, dimensions, at least two loads and support conditions
logically so that it can deflect freely to the maximum limit.
(b) Will the beam designed in part (a) withstand the stresses. Explain.
1. Was there good agreement between the theoretical predictions (dthe) and the experimentally
measured (dexp ) deflection? Why?
2. Is the theoretical analysis conservative or does it understate the actual deflection? Explain?
3. Does the distance between the supports effects the deflection measured? Why?
4. How does the moment of inertia affect the deflection?
5. Aluminum and copper of same geometric dimensions, which will deflect more? Why?
